Type of Soil Possible Solution
Dry sugar, sugar syrup, milk or
tomato spills. Melted plastic film or
foil. All these items REQUIRE
IMMEDIATE REMOVAL. Failure to
remove these immediately can
permanently damage the surface.
Remove these types of spills while the
surface is hot using the razor blade
scraper. Use a new, sharp razor in the
scraper.
Remove pan and turn off the element.
Wearing an oven mitt, hold scraper at 30 o
angle, using care not to gouge or scratch
the glass. Push soil off the heated area.
After the surface has cooled, remove the
residue and apply the glass ceramic
cooktop cleaner.
Greasy spatters Use a soapy sponge or cloth to remove
grease; rinse thoroughly and dry. Apply
glass ceramic cooktop cleaner.
Metal marks: Iridescent stain Pans with aluminum, copper or stainless
steel bases may leave marks. Treat
immediately after surface has cooled with
glass ceramic cooktop cleaner. If this
does not remove the marks, try a mild
abrasive (Bon Ami  , Soft Scrub  without
bleach) with a damp paper towel. Rinse
and reapply crème. Failure to remove
metal marks before the next heating
makes removal very difficult.
Hard Water Spots
Hot cooking liquids dripped on surface
Minerals in some water can be transferred
onto the surface and cause stains. Use
undiluted white vinegar, rinse and dry.
Recondition with glass ceramic cooktop
cleaner. Remove boilovers and stains,
before using the cooktop again.
Surface scratches
Small scratches are common and do
not affect cooking. They become
smoother and less noticeable with daily
use of the glass ceramic cooktop
cleaner.
Apply glass ceramic cooktop cleaner
before using to remove sand-like grains
and grit such as salt and seasoning.
Can be reduced by using pans with bases
that are smooth, clean, and dry before
use.
Use recommended glass ceramic
cooktop cleaner daily.
Be Careful: Diamond rings will scratch
the surface.
The sensor window on the Sensor Dome  must always be kept clean. Remove
splattered grease and dirt regularly. Use cotton swabs or a soft cloth with dish
detergent or glass cleaner, such as Windex  to do this.
